Surat Al-Israa (The Night Journey) - الإسراء

قُلِ ٱدْعُوا۟ ٱللَّهَ أَوِ ٱدْعُوا۟ ٱلرَّحْمَٰنَ أَيًّا مَّا تَدْعُوا۟ فَلَهُ ٱلْأَسْمَآءُ ٱلْحُسْنَىٰ وَلَا تَجْهَرْ بِصَلَاتِكَ وَلَا تُخَافِتْ بِهَا وَٱبْتَغِ بَيْنَ ذَٰلِكَ سَبِيلًا ﴿١١٠﴾

Say: Call upon Allah or call upon, the Beneficent Allah; whichever you call upon, He has the best names; and do not utter your prayer with a very raised voice nor be silent with regard to it, and seek a way between these.
